rn-UNING LADDER.

Application filed March a1, 1922] Seria1 No. 545,498. I

To all 20 item it may concern Be it known that we, SYLVESTER J. MrroHnLL, ALFRED D. GABBERT, and JoHN IV. BLATTER, citizens of the United States residing at Grand Junction, county of Mesa, and State of Colorado, have invented certain new and useful Improvements in Pruning Ladders, of which the following is a specification.

Our invention relates to platform ladders designed to be used for pruning and pick ing purposes in orchards and the like, and it has particular reference to a. portable ladder so mounted as to be readily accessible at all times and which may be utilized in moving the ladder member from tree to tree or various points, without moving the base upon which the ladder is mounted.

The primary object of the invention is to provide a pruning and picking ladder With these and such other objects in view,

as will be apparent from the description, our invention resides in the novel combination, construction, and arrangement of parts hereinafter described and claimed, and illustrated in the accompanying drawings. in which Figure 1 is a side elevation of the preferred form of the invention;

Figure 2, a top plan view thereof;

Figure 3, a transverse section throughthe support showing the ladder in extended position; and

Figure 4, a similar section showing a ladder when disposed in folded position.

In detail, the invention comprises a relatively large rectangular base 1, suitably supported on longitudinal beams 2, and having mounted thereon at opposite ends transverse beams 3, between which are disposed at opposite side edges of the base longitudinally extending rods 4 supported in this on the end beams 3 in suitable retaining members 5. By this construction the rods 4 are supported in spaced relation from the base 1 and their central portions are supported against sagging by means of the brace bearings 6 disposedsubstantially centrally of the base. Y j

Inclined ladders 7 are pivoted at their lower ends on the rod 4 at one side of the sleeve members 10 longitudinally slidable on the opposite rod 4, whereby whenthe,

ladders are moved longitudinally of the support the guy. wires may be carried likewise with perfect freedom'of movement.

When in folded position, the ladders 7 are folded upon the base 1 with their outer ends resting on the'rod- 4 which carries the guy wire sleeve members. In this preferred form, the base 1 is shown as a framework adapted to be rested on the ground at the base of the trees and the like, but itis obvious that the same may be supported on a wagon and moved from place to place or mounted on wheels or skids as desired,

scope of the invention.

While we have describedandillustrated preferred form, certain details of without in anyway departing from the construction, we do not intend to limit ourselves to these. but any such may be used as will fall within the scope of the invention as claimed. a

We claim:

A pruning ladder comprising a portable, fiat, rectangular base adapted to be mounted on a wagon body, transverse beams at opposite ends thereof, longitudinally disposed rods carried by said beams along opposite sides of the base and in spaced relation thereabove, a ladder pivoted at. its lower end on one of said rods and foldable over said base with its upper end adapted to be supported on the other of said rods,

one end to said sleeve and at the. opposite end to an upper rung of the ladder, whereby said ladder, wire, and sleeve may be moved longitudinally of the base and maintained in raised position, the length of said wire 10 being such as to dispose said. ladder when raised inclined outwardly of the base.

In testimony whereof we afiiX our signatures.
